'rrrnwnrrme MACHINE.

Application filed July 5,

of the general-type-disclos'ed in my Patent 1N0. 1,417,??72, dated May23, 1922. In the ordinary operation of writing and forms on a t ewriter,a great deal of time is lost by aving to interleave the sheets withcarbon paper and then setting the sheets in the machine preparatory tothe Writing operation. Time is also lost by having to disassemble thesesame sheets after the typing is finished.

Also this is true in the ordinary method of filling out forms andsimultaneously. making manifold copies thereof as, for example, inmaking out insurance forms by fillin in the necessar data in spacesrovided in rinted blan s, the original 0 the policy eing delivered tothe party insured and one or more copies thereof being preserved in thefiles of the insurance company and the insurance agency. Theusualoperation involves selecting from the filing case in which the formblanks are stored the 'required number of copies of the form blank,interleaving and assembling these blanks with the necessary number ofcarbon sheets and-inserting and positioning these interleaved andassembledblanksin the typewriter, all of which must be done before thework of filling in the forms is commenced, thereby consuming inpreparation for the work a considerable amountof time in proportion tothe time needed for the actual making out of the forms.

The present invention has, therefore, for a primaryobi'ect the provisionof 'means whereby this use of time in selecting the sheets interleavingthem with carbon-paper, assembling them together and insertin them inthe machine may be reatl'y reduce and the required number'of preparedwith a minimum expenditure of timeend eflortj v i Another ob'ect-of-thsinvention is to 1'0- vide means w ereby a considerable .stocof plain writing paper letter-heads, or blanks for each-cf a num erof-diiierent,=iorms,

; invention to uplicate copies 1922. Serial No. 578,080.

maybe conveniently stored and rendered quickly available for the purposeof preparing the required number of copies of a policy or other documentfrom any of said forms.

It is also an object of the invention to provide means for iacilitatinthe introduction of the required blanks, lb plain sheets, into th e.proper writing osition with reference to a typewriter, an foreliminating the necessity of excessive care on the art of the operatorordinarily required in setting up the work-sheets and transfer materialto insure the pro er manipulation and operation of the mec anism.

It is a further object of the invention to provide a mechanism in whicha considerable saving in carbon or transfer material is obtains and-inwhich there is required no handling of this carbon ortransfer paper bythe operator so that soiling ofthe fingers and the resultant soiling othe paper is eliminated.

And it is a still provide a device of this type in which the operationof making erasures is facilitated.

With the foregoingund other objects in view I have devised the novelmechanism illustrated, in the accompanying drawings, in which Fig. 1 isatype of writing machine with my improvements complete.

Mounted on one-ofthe-end members, prefterebly'the left hendon'e' shownat Figs-3, 4,

(i ll and 7, are suitable supports for the supply of. transfer materialwhich transfer material is preferably in the form of a narrow web 51,Figs. 3 and 4, and is wound in flat rolls of suitable size as indicatedat 52. The supports for these rolls comprise studs 53 secured to theframe and carry a core 54 upon which the rolls 52 may be placed therebeing guiding and holding discs 55 and 56 mounted on these studs betweenwhich the rolls 52 are mounted. The core 54 is secured to the inner disc55 and also secured to this disc on the other side thereof is thetoothed ratchet or disc 57. The outer guide disc 56 is loose on thestud-53 and is yieldingly held against the end of the core 54 and theroll 52 of transfer material mounted thereon by means of a coil spring58 secured on the studs by suitable nuts 59, with a suitable washer 60between the spring and the disc. Mounted on the supporting means for theplaten 33 is a toothed disc 61 adapted when the platen is rotated toreciprocate a bar 62. this bar being held at its lower end against theguiding pin 63 and in contact with the disc 61 by means of a spring 64which is secured to the bar 62 at 65. This bar is pivotally connected at66 to escapement elements 67, these elements being pivoted to the frameat 68 and connected so as to move simultaneously by means of a link 69pivoted to the same at 66 and 70. These escapement elements are providedwith spaced fingers 71 and 72 which are adapted to cooperate with theteeth of the discs 57 when the ratchet elements are rocked as the bar 62is reciprocated and allow the discs 57 and the rolls of the transferwebs to which they are attached to rotate to supply the transfer webs ascalled for by the feeding! mechanism in a manner presently to bedescribed. One of the escapement elements 67 is provided with a button73 which may be pressed by the operator to engage the upper fingers 71with the ratchet discs and hold the bar 62 out of contact with theratchet 61 so that the platen may be rotated without affecting the escaement mechanism.

1V ounted at the other end of the frame is a drum 74 upon which the usedweb may be wound. At the opposite end of this drum are the discs 75 and7'6 and this drum may be rotated by hand by means of the knob 77. Thisknob and the outer disc are remoiably scoured to the drum by anysuitable means such as a screw threaded engagement therewith. Alsoconnected with this drum on the opposite side of the cod of the frame,is another drum or cup 78 within which is located a convolutc spring 79frictionally engaging the inner walls of this cup as shown at 80, Fig.8, and secured at its inner end to a shaft 81 rigidly connected with agear 82. This gear meshes with the idler 83 which in turn meshes withthe gear 84 secured to the platen so that rotation of the platen in thedirection indicated by the a!" row in Fig. 8 will rotate the gear 82 inthe same direction and will tend to wind the s iring T9. The friction ofthe spring against t e cup or drum 78 will also tend to rotate the drum74 to wind the web thereon but, as there is frictional engagement onlybetween the spring and the cup, the gear 82 and, therefore, the platenmay if desired be rotated without feeding; the transfer web or websacross the front of the platen when the button 73 is depressed and thesupply drums 52 are, therefore, held against rotation. The disc 76 isprovided on its periphery with teeth 85 adapted to coact with a springpressed pawl 86 to prevent reverse movement of the drum 74. The gear 84is loose on the platen shaft 87 and is rotated counterclockwise asviewed in Fig. 8, or clockwise as viewed in Fig. 11, by means ofatoothed disc 88 secured to the shaft 87 and adapted to enact with aspring: pressed pawl 89 carried by the gear 84. It will thus be seenthat' rotation of the shaft 87 counterclockwise asiviewed in Fig. 8, orclockwise as viewed iinFig. 11 will rotate the gear 84 therewith bin.the platen shaft ma be rotated in the opposite direction wit outrotating the gear.

The transfer webs are guided in the passage from the supply drums o-rrolls of web 52, Fig. 3, across the front of the platen to the drum 74by suitable guiding means. At

the left hand of the platen, as shown in;

Fig. 3, and mounted on the end of the frame is a hollow pin or tube 106,Fig. 13, pla ed at an angle of substantially 45 and wlun a single carboncopy is made the single transfor web required is passed from eithersupply drum under the guide pin 108, Fig. 3, and then around the outsideof the tube 106, as shown in Fig. 13, and then goes between the guidefingers 109, Fir-. 3, horizontally across in front of the platen 33, asshown in Fig. 3, over another guide 11.0 placed at 45, undcr a secondguide pin 111 and then to the drum 74. make two carbon copies twotransfer webs are required and as they are both wound up on the drum 74the outer web 112 must travel slightly faster than the inner web. Ifthose webs are both passed over the guide tube 106, Fig. 13, in con actwith each other, as the outer web moves slightly faster than thc innerweb and it cannot pass the inner web it will cause this inner wcb toslacken in front of the platen. Therefore. to prevent this l provide aso aratiug; means prefcrably an additional guiding means as shown nFigs. 13, 14. and 15 comprising a pin 113 adapted to be inserted in theupper end of the. guide iubc 106 by means of a knob 114. This pincarries a semi-circular shield 115 spaced from the pin 113 a suitableamount However, when it is desired to 101 norm ally so that when the pin113 is inserted in the tube 106 the inner surface of this shield will bespaced from the outer surface of the tube to allow the passage of theinner web 107. The outer web 112 passes around the outs de of the shieldU5 and so is maintained out of contact with the inner web.

Secured within the frame above the platen is a guide plate 90 havingguide fingers 90' secured thereto adjacent its upper edge and extendingupwardly in front of roll l9. The plate is provided with vert cal Slots91 adjacent its opposite ends in which is adjustably mounted a knifeblade 92 by any suitable means such as the nut 93, Fi 12, threaded onthe sleeve 94 which has a ange 95 bearing against the front surface ofthis plate. By loosening this nut the knife may be adjusted in the slotsand then secured in adjusted position. Mounted to rotate in the sleeves94 are pins 96 provided in their surfaces with a spiral groove 97 andthe knife blade 92 is adapted to slide longitu dinally of the sleeve 94on the outside thereof as shown in Fig. 12. The sleeve is provided witha longitudinal slot 98 through which lug 99 carried by the knife bladeprojects, this lug also extending into the spiral groove 97. Rigidlysecured to pin 96 by any suitable means as a screw 100 so as to movewith this pin, are guide fingers in front of the plate 90 as shown inFig. 3 to hold the free ends of the sheets of paper in an uprightposition after they come off the platen. The knife blade 92 is normallyspaced a distanee'forwardly of the plate 90 as shown in Figs. 5 and 12to allow free passage of the sheets of paper. When it is desired tosever the sheets of paper the operator presses the knife blade inwardlyand clamps the sheets of paier between this blade and the plate 90. 'lis operation, through the action of the lugs 99, Fig. 12, in the spiralgrooves 97, rotates the pins 96 and swings the guide fingers 101outwardl toward the ends of the frame leaving t e space in front of thesheets of paper free and unobstructed so that these sheets above theknife blade may be torn oil along the upper edge thereof. Upon removalof pressure from the knife it is moved outwardly to its normal positionby the springs 94 which movement also returns the guide"fingers .101 totheir normal upri ht positiorl in front of plate 90.

When the carrier is removed from the machine the free ends of the papershould be secured to prevent their dropping away from the platen to besure that they are always in proper writing position when the carrier ismounted in writing position on the carria Various means may provided foroing this but I hays shown the spring elements 102, Fig. 3, pivoted tothe knife blade 92 at 108 and being bent be the top edge of the kniferearwardly so that, when in the position shown in Fig. 3, they mayproject throu h elongated openings 104 in the knife bla e and clamp thefree ends of paper against the plates 90. These springs may be pulledforwardly and moved to one side of the openings 104 and thus release thepaper by means of suitable handles or knobs 105.

The operation is as follows:

When it is desired to use this attachment, the regular platen 23 isremoved from the carriage 21 by sliding back the guides 26 and liftingthe platen from the carriage. This attachment or carrier including theframe, platen, work-sheets, transfer material, and means for holding andfeeding the same, is placed on the carriage in place of the platen thathas just been removed, the platen 33 in the attachment occupying theposition of the old platen 23 enacting in the same manner with the typebars and adapted to be rotated by the spacing mechanism 40 in the sameas was the old platen. As this platen is rotated, it draws from therolls 49 the paper P the free ends of which have been passed aroundunder the platen and properly located with respect to the trans er websand then passed between the knife 92 and the guide plate 90. Rotation ofthe platen step by step in the writing operation will rotate the drum74: through the gears 82, 83, S4 and the spring 79, Fig. 8, and wind 11the used transfer web as fast as this we is released by the escape-Inent mechanismpn the supply rolls As this escapement mechanism isoperated by the rotation of the laten, if it is desired to advance thework-sheets for any reason by hand, this may be done by means of theknobs 38 in the usual manner. However as it is undesirable when doing soto advance and thus waste the transfer web, the operator by pressing onthe button 73 may hold the supply drums against rotation and the spring79 will then slide relative to the cup or drum 78. It will he apparentthat as this drum is rotated through the instrumentality of the springafter it. is wound or placed under tension, the transfer web will alwaysbe held under tension from this spring and so will always be held tautacross the front of the p aten. After the writing has been complet thesheets may be advanced as just descri d to the proper tearing ofiposition, when the operator resses against the front edge of the knifelilade 92 clamping the sheets against the guide plate 90 and moving theguide fingers 101'from in front of the sheets to the opppsite edgesthereof. The sheets may then sevfiree by blade. The knife blade beingthen released is moved to its forward position and the guide fingers 101are turned to holding position as shown'in drawing them forwardly overFig. 3 by the springs 94. If now it is dcsired to remove the attachmentand use the old platen. the holding springs .102 are placed in holdingposition, the slides 26 moved To releasing position and the entireattachment removed from the machine by lifting the same from thecarriage. In using the old form of platen. holding clips are usuallyprovided at the front thereof such as pivoted plates U7, Figs. .ic and16, carrying rollers 118 and yieldingiy held against the platen. I haveprovided means for holding these clips forwardly so they will notinterfere wilh the insertion of the platens, such angle shaped elements119 secured to the carriage at 120.

It will be apparent from the foregoing description that the carrierincluding the platen. supply of worksheets and transfer material may bereadily applied to and re moved from the machine WltllOlll the use oftools of any kind, and that as the Worksheets and transfer material areall set up in the attachment and are in continuous rolls, assembling andsetting up of the individunl sheets is unnecessary and the time re uiredfor these operations which is consi erable is eliminated. Also as thereis no handling of the transfer material by the operator there is nosoiling of the fingers or the work-sheets. Further, as he transfermaterial is in the form of a narrow web and is fed across in the frontof the platen in a direction transverse to the direction of feed of theWork-sheets, if any erasures are re quired' they may be made by slightiyadvancing the Work-sheets and performing the erasing operation withoutthe necessity of inserting a guard between the transfer paper and thecarbon copy. There is material saving in the amount of transfer paperrequired as all the transfer paper is used uniformly, the feed thereofbeing proportional to the amount of writing donc instead of the amountof work-sheets and paper passed through the machine as in the ordinarymethod.

In the typewriter employed the regular platen is rcadilv removable fromthe re ciprocating mechanism and in my device the carrier unitcomprising the platen. worksheets. and carbon paper or transferniaterial is adapted to be connected with the said reciprocatingmechanism of the typewriter. which includes a tension and escape,- mcnfmechanism, by the some m ans. so that this carrier is also readilyremovable to allow the operator to quickly and easily con neck thiscarrier unit with and disconnect it from said reciprocating mechanism.thereby making the carrier unit freely interchangeable with the reguhnplaten provided.

on the machine. The connection or relation between the carrier unit orthe regular platen carried by the machine to the recipl'UCHl ingnuchenismis such that the carrier unit or regular platen may be readildisconnected and removed therefrom without breaking down therecipocnting mechanism.

In short in applicants device the carrier 7 unit and the regular platenare freely interchangeable and one may be removed from the typewriterand the other placed in posi lion thereon without breaking down any partof the typewriter, carrier, or regular 15 platen. or changing either onein any way.
